列出指定功能的按键和按键组合
# bind -q abort//请用 调用abort “C-g”, “C-xC-g”, “eC-g”.# bind -q accept-line //列出功能“accept-line”按键以及组合按键//请用 调用accept-line “C-j”, “C-m”.
bind -x '"\C-l":ls -l' #直接按 CTRL+L 就列出目录
其中keyseq可以使用showkey -a命令来获取：
[root@localhost ~]# showkey -aPress any keys - Ctrl-D will terminate this program^[[A 27 0033 0x1b 上 91 0133 0x5b 65 0101 0x41^[[B 27 0033 0x1b 下 91 0133 0x5b 66 0102 0x42^[[D 27 0033 0x1b 左 91 0133 0x5b 68 0104 0x44^[[C 27 0033 0x1b 右 91 0133 0x5b 67 0103 0x43 32 0040 0x20^M 13 0015 0x0d 字母M^C 3 0003 0x03 Ctrl-C^D 4 0004 0x04 Ctrl-D 退出
